Our Team

Mats Bertilsson, founder & Innovator

Mats have a vision together with all Teknik Supports suppliers to create better working conditions for one of the most dangerous environments in the pulp mill industry. Mats is the founder and innovator behind Teknik Support, bringing together strong academic knowledge and decades of hands-on industrial experience. He holds a degree in Engineering Mechanics from Chalmers University of Technology in Gothenburg and has extensive experience in the design and development of advanced machine constructions, including automatic air port rodders for recovery boilers. With solid expertise in project management, Mats founded Teknik Support in 1995, following several years of work within the forest and process industries. Since then, he has worked on-site at pulp mills in Sweden, Finland, Spain, and Brazil, gaining deep insight into real operating conditions and customer needs. Mats’ background in machining (turning and milling) and mechanical maintenance gives him a unique ability to bridge engineering, production, and operation. This practical knowledge enables efficient collaboration with suppliers and ensures that all solutions are designed with a strong focus on simplicity, reliability, and low maintenance costs. Highly engaged throughout the entire development process, Mats actively participates from initial idea and design to testing in the workshop and final implementation at the mills. His hands-on approach and commitment to practical innovation ensure that Teknik Support delivers robust, proven solutions tailored to some of the most demanding industrial environments.

Johan Engvall – Business Development

Johan’s vision is to make the highest safety standards on the smelt spout deck a global benchmark for pulp and paper mills with recovery boilers. Through Teknik Support’s smelt spout robot, the most hazardous manual tasks identified by BLRBAC are replaced with a robust and proven automated solution — significantly improving personnel safety in one of the industry’s most critical environments.
Johan joined Teknik Support in 2025 and works with business development, supporting recovery boiler customers in reducing risk, improving safety, and securing stable long-term operation.
He is an engineer with more than 30 years of international experience in the pulp and paper industry. Johan spent 23 years at Diamond Power Sweden AB as Product Manager for port rodding systems and infrared char bed camera systems —equipment used in some of the most safety-critical areas of recovery boiler operation.
Throughout his career, Johan has visited 138 recovery boilers across 39 countries on every continent. He works closely with operators, maintenance teams, and plant management to deliver practical solutions that improve safety, performance, and long-term reliability. This extensive field experience provides a deep understanding of recovery boiler safety challenges, operational limitations, and the importance of reliable, well-engineered solutions.
Johan’s focus is on long-term customer value. Together with customers, he works to identify the safest and most effective solutions for each boiler, aligned with Teknik Support’s philosophy of replacing high-risk manual work with robust, proven automation designed for demanding recovery boiler environments.
